From the Flight Deck to the Bedside: Core Aviation Concepts Applied to Acute Care Physical Therapist Practice and Education.

The health care industry has sought to reduce errors and patient harm by drawing upon human factors research developed largely in the aviation industry. However, literature that explicitly applies human factors concepts to physical therapist practice is scarce. Therefore, this clinical perspective highlights the key concepts in aviation safety and training that should be considered for application to physical therapist education and practice in the acute care setting, including the law of primacy, pilot in command, crew resource management, situational awareness, the instrument scan, currency versus proficiency, the advanced qualification program, and the use of checklists. The authors identify, discuss, and apply existing parallel concepts in physical therapist literature. The authors then challenge acute care physical therapists, academic faculty, and clinical instructors on ways to integrate these concepts in practice.

Effects of nordic walking exercise on gait, motor/non-motor symptoms, and serum brain-derived neurotrophic factor in individuals with Parkinson's disease.

Objective: The primary purpose of this study was to investigate the immediate and long-term effects of Nordic Walking (NW) exercise on walking function, motor/non-motor Parkinson's Disease (PD) symptoms, and serum brain-derived neurotrophic factor (BDNF) in persons with idiopathic PD. Methods: Twelve community-dwelling participants with mild to moderate idiopathic PD and varied degrees of gait dysfunction were recruited for this prospective, repeated measures design that examined clinical measures and BDNF levels at baseline (T0), post-intervention (T1) and 3-month follow-up (T2). Participants engaged in 6 weeks of supervised NW exercise training with individualized instruction, followed by 14 weeks of independent NW exercise with remote coaching. Outcome measurements included daily step counts, 6-Minute Walk Test (6-MinWT), 10-Meter Walk Test (10MWT), spatiotemporalparameters, Timed Up and Go Test (TUG), dual-task TUG, Revised-Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS), Revised-Freezing of Gait Questionnaire, MDS-Nonmotor Symptom scale (NMS), Parkinson's Fatigue Scale, and serum BDNF levels. The Friedman test with post hoc Wilcoxon sign-ranked pairwise comparisons were used to compare baseline to T1, baseline to T2, and T1 to T2 timepoints with a Benjamini-Hockberg correction applied. Results: Statistically significant improvements found post-training and retained at 3-month follow-up included 6-MinWT, daily step count, 10mWT, MDS-UPDRS, and TUG with effect sizes of 0.57 to 1.03. Serum BDNF at T2 was significantly greater than T0 and T1. Although no statistically significant improvements were observed in the MDS-NMS, 9 of 12 participants had improved non-motor symptoms. There was good adherence, sustained independent exercise engagement, and no adverse events over the 5-month study duration. Conclusions: This study demonstrated that NW exercise was a safe, feasible, and sustainable mode of aerobic exercise for this sample of participants with varied Parkinson's disease duration and severity. Following an individualized and progressive NW training intervention, significant improvements in walking function, daily activity level, and motor function were observed. Following the supervised NW training phase, independent three-month engagement in NW exercise was sustained with long-term retention of these clinical improvements and an increase in serum BDNF levels over this five-month NW exercise trial. Impact: Nordic walking exercise may be a safe, feasible and sustainable mode of independent exercise for improving daily ambulatory activity, gait and motor function, and serum BDNF in individuals with mild to moderate PD with varied gait abilities.

Dynamic factor analysis of seasonal variation in daily physical activity in individuals with heart failure and implanted cardiac devices.

BACKGROUND: The purpose of the present study was to determine the presence and magnitude of seasonal variation in daily physical activity (PA) in those with heart failure (HF). METHODS: Retrospective study and dynamic factor analysis (DFA) of Patient Activity data from Medtronic implanted cardioverter defibrillator and cardiac resynchronization devices (ICD/CRTs). RESULTS: In a data set of 435 patients, distinct states/trends were identified by DFA including a classic, sinusoidal pattern of seasonal variation and a pattern of decline over the course of 12 months, which were associated with specific clinical characteristics. Overall, model fitting was good. CONCLUSIONS: Those with low comorbidities, better NYHA Class, higher BMI, no hospitalization, and male sex demonstrated greater seasonal variation of at least 40 min per day between winter (lowest PA) and spring/summer (highest PA). Those with female sex and hospitalization demonstrated overall downward trajectories of approximately 40 and 80 min, respectively, over the course of the year.

Subjective Daily Physical Activity Measures in Heart Disease: A Systematic Review.

BACKGROUND: The measurement of daily physical activity (DPA) is important for the prognosis and quantifying clinical outcomes in individuals with heart disease. The measurement of DPA is more feasible using subjective measures when compared with objective measures. The purpose of this systematic review of the literature was to identify the subjective measures of DPA that have established reliability and validity in individuals with heart disease to assist clinician and researcher instrument selection. METHODS: A systematic search of PubMed, CINAHL, MEDLINE, and ProQuest databases was performed. Methodological rigor was assessed using 3 different quality appraisal tools. Qualitative synthesis of included studies was performed. RESULTS: Twenty-two unique studies covering 19 subjective DPA measures were ultimately included. Methodological rigor was generally fair, and validity coefficients were moderate at best. CONCLUSIONS: Only 4 subjective measures that have established test-retest reliability and that provide an estimate of energy expenditure, metabolic equivalents, or minutes of DPA were compared against accelerometry or a DPA diary in patients with heart disease: SWISS Physical Activity Questionnaire, Total Activity Measure 1 and 2, and Mobile Physical Activity Logger. Depending on the clinician or researcher needs, instrument selection would depend on the recall period and the DPA construct being measured.

A Knowledge Translation Framework for Optimizing Physical Therapy in Patients With Heart Failure.

The American Physical Therapy Association has supported the development of clinical practice guidelines to promote and support evidence-based practice and reduce unwarranted practice variation. Essential to the success of this effort is the generation of knowledge translation, a concept that emphasizes the translation of global knowledge to an application that can be effectively integrated into clinical practice. The Physical Therapy Clinical Practice Guideline for the Management of Individuals with Heart Failure published in the Physical Therapy Journal in January 2020 provides a broad base of knowledge related to evidence-based treatment interventions for patients with heart failure. However, the application and integration of this knowledge in clinical practice need further elucidation. Therefore, this perspective paper aims to serve as a complementary knowledge translation resource to the recently published practice guideline to maximize the utilization of contemporary evidence in clinical practice. This resource provides the physical therapist with practical guidance in the management of patients with heart failure by placing research findings in the context of other knowledge and practice norms that can be applied at the point of care and across the continuum of care. We propose a novel ABCDE (assessment, behavior modification, cardiorespiratory fitness, dosage, and education) practical framework. This clinical paradigm is grounded in ongoing physical therapist assessment throughout the episode of care, along with behavior modification, assessment of cardiorespiratory fitness, appropriate selection and dosing of interventions, and patient education. Examples highlighting the use of this model in patients with heart failure across the continuum of care are provided for application in clinical care.

Physical Therapist Clinical Practice Guideline for the Management of Individuals With Heart Failure.

The American Physical Therapy Association (APTA), in conjunction with the Cardiovascular and Pulmonary Section of APTA, have commissioned the development of this clinical practice guideline to assist physical therapists in their clinical decision making when managing patients with heart failure. Physical therapists treat patients with varying degrees of impairments and limitations in activity and participation associated with heart failure pathology across the continuum of care. This document will guide physical therapist practice in the examination and treatment of patients with a known diagnosis of heart failure. The development of this clinical practice guideline followed a structured process and resulted in 9 key action statements to guide physical therapist practice. The level and quality of available evidence were graded based on specific criteria to determine the strength of each action statement. Clinical algorithms were developed to guide the physical therapist in appropriate clinical decision making. Physical therapists are encouraged to work collaboratively with other members of the health care team in implementing these action statements to improve the activity, participation, and quality of life in individuals with heart failure and reduce the incidence of heart failure-related re-admissions.

Quantification of Seasonal Variation in Daily Physical Activity in Individuals with Heart Failure and Implantable Cardioverter Defibrillator/Cardiac Resynchronisation Therapy Devices.

PURPOSE: Understanding seasonal variation of daily physical activity (PA) in patients with heart failure (HF) has important implications for planning and interpretation of clinical trials, but the presence and magnitude of this seasonal variation in daily PA have yet to be established. The purpose of the present study was to determine the presence and magnitude of seasonal variation in daily PA in community-dwelling individuals with HF using several analytic approaches. METHODS: Retrospective chart review of patients with HF and Medtronic implantable cardioverter defibrillator/cardiac resynchronisation therapy (ICD/CRT) devices. Data included in analyses (autocorrelation, analysis of covariance, one-way analysis of variance) were clinical characteristics, the patient activity measure of daily PA from the ICD/CRT devices, temperature and hours of daylight over the 1-year period of 1 November 2017-31 October 2018. RESULTS: One hundred and sixty-eight patients were included. Visual analysis and autocorrelation demonstrated seasonal variation in daily PA. Daily PA seasonal difference between winter and summer months was 0.4 hours per day/24 minutes per day/2.8 hours per week/14.9%. This seasonal effect on daily PA is significantly greater in those with ≤8 comorbid conditions and an overall activity level of >2.2 hours per day compared to those with multiple comorbidities and low overall activity (0.7 versus 0.1 hours per day, respectively). CONCLUSIONS: The present study affirms the seasonality of daily PA in a cohort of patients with HF and ICD/CRT devices and reveals a disproportionate seasonal effect on those with fewer comorbidities and higher overall activity levels. Seasonal variation should be accounted for when interpreting change in daily PA in clinical practice and when designing and interpreting results of clinical trials investigating interventions to improve daily PA.

Early Access to Physical Therapy and Specialty Care Management for American Workers With Musculoskeletal Injuries.

OBJECTIVE: The aim of this study was to investigate the effect of very early access to physical therapy and specialty care management in a workers' compensation population. METHODS: A prospective pilot (n = 75) was conducted from 2012 to 2013 in which injured workers with musculoskeletal complaints received physical therapy and started care management during their initial occupational medicine clinic visit. Two retrospective comparator groups with workers' compensation claims from 2009 and 2012 were included in this study. RESULTS: When comparing 2009 data with the 2012 to 2013 prospective pilot study, statistically significant differences were noted in favor of the prospective pilot for total costs per claim, cost of indemnity, number of therapy visits, and time to access physical therapy. When compared with the 2012 nonpilot cohort, differences were not statistically significant. CONCLUSIONS: Expedited access to physical therapy and care management can reduce duration of care, cost of claims, and therapy visits.

Seasonal variation of daily physical activity in individuals with heart failure.

BACKGROUND: Previous studies indicate that seasonal variation affects daily physical activity (PA), but none have investigated this relationship in individuals with heart failure (HF) who also have implanted cardioverter defibrillators and cardiac resynchronization therapy (ICD/CRT) devices. The purpose of the present study was to determine if seasonal variation in temperature affects daily PA in patients with HF and ICD/CRTs. PATIENTS AND METHODS: Secondary analysis of data from 16 subjects with HF and Medtronic® ICD/CRT devices enrolled in a randomized trial investigating interventions to improve daily PA. Due to the rolling study enrollment, daily PA data for all subjects were not available for the entire time frame and were divided into two groups. Determination of seasonal variation of daily PA was determined using visual analysis of daily PA plotted with average temperature, autocorrelation, visual analysis of seasonal subseries plots and boxplot analysis, as well as Wilcoxon signed-rank tests. RESULTS: Subjects 1-8 demonstrated the greatest differences in daily PA during periods of seasonal transition whereas subjects 9-16 demonstrated the greatest variation in daily PA with greatest seasonal temperature difference. Wilcoxon signed-rank testing of the lowest and highest months for daily PA revealed median differences of 0.30 (p = 0.050) and 0.36 hours (p = 0.036) for subjects 1-8 and 9-16, with effect sizes of 0.69 and 0.74, respectively. CONCLUSIONS: Seasonal variation in mean temperature appears to affect daily PA in individuals with HF and ICD/CRT devices by a magnitude of 0.30-0.36 hours, which may need to be accounted for in future research investigating interventions to improve daily PA.

Replicable Interprofessional Competency Outcomes from High-Volume, Inter-Institutional, Interprofessional Simulation.

There are significant limitations among the few prior studies that have examined the development and implementation of interprofessional education (IPE) experiences to accommodate a high volume of students from several disciplines and from different institutions. The present study addressed these gaps by seeking to determine the extent to which a single, large, inter-institutional, and IPE simulation event improves student perceptions of the importance and relevance of IPE and simulation as a learning modality, whether there is a difference in students' perceptions among disciplines, and whether the results are reproducible. A total of 290 medical, nursing, pharmacy, and physical therapy students participated in one of two large, inter-institutional, IPE simulation events. Measurements included student perceptions about their simulation experience using the Attitude Towards Teamwork in Training Undergoing Designed Educational Simulation (ATTITUDES) Questionnaire and open-ended questions related to teamwork and communication. Results demonstrated a statistically significant improvement across all ATTITUDES subscales, while time management, role confusion, collaboration, and mutual support emerged as significant themes. Results of the present study indicate that a single IPE simulation event can reproducibly result in significant and educationally meaningful improvements in student perceptions towards teamwork, IPE, and simulation as a learning modality.

A virtual patient educational activity to improve interprofessional competencies: A randomized trial.

The purpose of the present study was to determine whether an interprofessional virtual patient educational activity improved interprofessional competencies in pharmacy, physician assistant, and physical therapy graduate students. Seventy-two fifth semester pharmacy (n = 33), fourth semester physician assistant (n = 27) and fourth semester physical therapy (n = 12) graduate students participated in the study. Participants were stratified by discipline and randomized into control (n = 38) and experimental groups (n = 34). At baseline and at study completion, all participants completed an original, investigator-developed survey that measured improvement in selected Interprofessional Education Collaborative (IPEC) competencies and the Readiness for Interprofessional Learning Scale (RIPLS). The experimental group had statistically significantly greater odds of improving on a variety of IPEC competencies and RIPLS items. The use of a single, interprofessional educational activity resulted in having a greater awareness of other professions' scopes of practice, what other professions have to offer a given patient and how different professions can collaborate in patient care.

Virtual patient care: an interprofessional education approach for physician assistant, physical therapy and occupational therapy students.

The purpose of this retrospective qualitative case report is to describe how a case-based, virtual patient interprofessional education (IPE) simulation activity was utilized to achieve physician assistant (PA), physical therapy (PT) and occupational therapy (OT) student IPE learning outcomes. Following completion of a virtual patient case, 30 PA, 46 PT and 24 OT students were required to develop a comprehensive, written treatment plan and respond to reflective questions. A qualitative analysis of the submitted written assignment was used to determine whether IPE learning objectives were met. Student responses revealed three themes that supported the learning objectives of the IPE experience: benefits of collaborative care, role clarification and relevance of the IPE experience for future practice. A case-based, IPE simulation activity for physician assistant and rehabilitation students using a computerized virtual patient software program effectively facilitated achievement of the IPE learning objectives, including development of greater student awareness of other professions and ways in which collaborative patient care can be provided.

The effects of speed-dependent treadmill training and rhythmic auditory-cued overground walking on gait function and fall risk in individuals with idiopathic Parkinson's disease: a randomized controlled trial.

OBJECTIVES: The purpose of this randomized controlled study was to examine and compare the immediate and retention effects of speed-dependent treadmill training (SDTT) and rhythmic auditory-cued (RAC) overground walking on gait function and fall risk in individuals with Parkinson's disease (PD). METHODS: Twenty participants (mean age 66.1 yrs) with idiopathic PD were randomized into either SDTT (n = 10) or RAC (n = 10) progressive, interval-based locomotor training protocols. Immediate and retention training effects on gait function and fall risk were measured by comfortable and fast gait speed (CGS, FGS), 6-Minute Walk Test (6MWT), and Functional Gait Assessment (FGA). RESULTS: Immediate within-group training effects revealed significant gains in CGS, 6MWT, and FGA for the RAC group, and in FGS, 6-MinuteWalk Test, and FGA for the SDTT group. Retention effects were found at 3-month follow-up for all gait measures in the RAC group, and for FGS and FGA in the SDTT group. No statistically significant differences in immediate or retention training effects on gait measures were found between groups. CONCLUSIONS: Externally-cued locomotor training with progressive and interval-based speed challenges, either with RAC overground or on a treadmill, produced significant improvements in walking speed, endurance, and dynamic balance during walking.

Clinically meaningful change estimates for the six-minute walk test and daily activity in individuals with chronic heart failure.

PURPOSE: The purpose of the present pilot study was to provide a preliminary estimate of the minimum detectable difference (MDD) and minimum clinically important difference (MCID) of the six-minute walk test (6MWT) and daily activity in outpatients with chronic heart failure (CHF). METHODS: A convenience sample of 22 adults with stable New York Heart Association Functional Class II and III CHF performed two baseline 6MWTs separated by 30 minutes of rest. Subjects then wore a triaxial accelerometer for 7 days to monitor daily activity. After 7 weeks of usual care, subjects again wore the accelerometer for 7 days and then returned to the clinic to complete the Global Rating of Change Scale (GRS) with regard to their heart disease and perform another set of 6MWTs. For the 6MWT, the MDD was calculated using the two baseline 6MWT distances. For daily activity, the MDD was calculated using two methods: (1) day-to-day test-retest reliability during baseline monitoring, and (2) baseline to follow-up test-retest reliability in those who reported no change on the GRS. The MCID for the 6MWT and daily activity was calculated using the mean and 95% confidence interval (CI95%) for those subjects who reported 'improvement' on the GRS. RESULTS: The MDD at the CI95% for the 6MWT was 32.4 meters. The MCID for the 6MWT was 30.1 (CI95% 20.8, 39.4) meters. The MDD for daily activity was 5,909 vector magnitude units (VMU·hr.(-1)) The MCID for daily activity was 1,337 VMU·hr.(-1) There was good alignment of the MDD and MCID for the 6MWT, suggesting that clinically meaningful change is approximately 32 meters. However, the calculated MCID was substantially less than measurement error as represented by the MDD, indicating that the MCID was underestimated in this sample or that daily activity may be robust to change in overall disease status.

Triangulating Clinically Meaningful Change in the Six-minute Walk Test in Individuals with Chronic Heart Failure: A Systematic Review.

PURPOSE: The purpose of the present review was to use existing, published data to provide an estimate of the amount of change in six-minute walk test distance (Δ6MWT) that represents a clinically meaningful change in individuals with chronic heart failure (CHF). METHODS: THE PRESENT REVIEW INCLUDED TWO SEPARATE LITERATURE SEARCHES OF THE CINAHL AND MEDLINE DATABASES FOR ARTICLES THAT: (1) reported the intraclass correlation coefficient (ICC) of the 6MWT in individuals with CHF, and (2) used the 6MWT along with either aerobic capacity or health-related quality of life (HRQL) as study endpoints in randomized controlled trials (RCTs) of exercise-based intervention for individuals with CHF. The ICCs were used to calculate the minimum detectable difference (MDD) at the 95% confidence interval for each included study. The Δ6MWT associated with aerobic capacity and HRQL within-group effect sizes for the intervention and control groups in each included RCT was analyzed using receiver operating characteristic (ROC) curves. RESULTS: Thirteen articles reported the ICC for the 6MWT. The mean (standard deviation) MDD calculated based on these data was 43.1(16.8) m. Eighteen RCTs measured the 6MWT and either aerobic capacity and/or HRQL. A Δ6MWT of 40-45 m was associated with at least moderate aerobic capacity and HRQL effect sizes in the intervention groups. The Δ6MWT thresholds that discriminated between intervention and control groups using ROC curves revealed the following sensitivity/specificity for the respective thresholds: 19 m, 94.4/83.3%, 32 m, 83.3/94.4%, and 48 m 44.4/100% (AUC = .935, p = .009, CI(95%) .855, 1.015). CONCLUSIONS: A Δ6MWT of approximately 45 m appears to exceed measurement error and be associated with significant changes in either aerobic capacity and/or HRQL.

Direct consumer access to physical therapy in Michigan: challenges to policy adoption.

Background. Michigan is 1 of only 4 states that require a physician referral or prescription before a consumer can receive treatment from a physical therapist.Objective. The purpose of the present analysis was to examine why the most recent attempts to pass direct access legislation in Michigan failed.Methods. The Policy Analysis Triangle approach, which considers the relevant actors, processes, and context in which a policy must be considered, was used to analyze legislative efforts to attain direct access in Michigan during the 2001­2002, 2003­2004, and 2005­2006 legislative sessions. Data sources included Michigan House and Senate legislative analyses, literature review, stakeholder position statements, political action committee contributions, and expert opinion.Results. Three successive direct access legislative attempts failed despite an increasing body of evidence supporting direct access and an increasing number of states allowing direct access. Proponents represented a relatively small number of individuals with limited political influence. Opponents represented a larger number of individuals who were able to exert greater political influence through large political action committee contributions and through physician legislators in positions of power who had influence over the bills' dispositions.Conclusions. Several prominent contextual and process-related barriers to policy adoption must be overcome in future attempts at direct access based on the findings from this analysis: (1) a limited constituency supporting direct access with regard to number of individuals and their political influence, (2) a perception that only the physician can independently diagnose and treat patient problems, and (3) legislators in positions of power who oppose a bill [corrected].

A method for providing high-volume interprofessional simulation encounters in physical and occupational therapy education programs.

With an increasing emphasis on interprofessional education within the allied health professions, simulation has potential for being a useful teaching modality for providing collaborative learning experiences for occupational and physical therapist students. However, there are many challenges associated with conducting simulations with large numbers of students. We describe the design, planning, cost, and support staff time required for conducting an interprofessional simulation of the intensive care setting, including a methodology for maximizing resources and student opportunities for participation for 64 physical and occupational therapy students over a 4-hour time period. Qualitative analyses of student experiences are also presented.

Inspiratory muscle training in patients with chronic obstructive pulmonary disease: the state of the evidence.

PURPOSE: The purpose of the present review was to assess the quality of evidence in the literature regarding the specific benefits of inspiratory muscle training (IMT) with an emphasis on training intensity and the relationships between changes in inspiratory muscle function and other clinical outcome measures. METHODS: Articles were found by searching CINAHL, PubMed, Medline via First Search, and ProQuest databases. Articles used in the review were randomized trials of IMT vs. sham IMT or no intervention, published in English in a peer-reviewed journal, included patients with chronic obstructive pulmonary disease (COPD), and specified the intensity of training. The quality of the studies was evaluated by 2 independent reviewers using the methodological rigor scale described by Medlicott and Harris as well as Sackett's levels of evidence. Fifteen articles met the inclusion criteria and were used in this review. RESULTS: Consistent improvements in maximal inspiratory pressures (ranging from -11 to -30 cm H(2)O) and inspiratory muscle endurance were found. Improvements in dyspnea and health-related quality of life were also observed. Inspiratory muscle training may result in improved exercise tolerance as measured using walking tests. High-intensity IMT resulted in improved training efficiency with respect to inspiratory muscle strength, but evidence of the effect of high-intensity IMT on other clinical outcomes is lacking. CONCLUSION: Despite research spanning decades, there are numerous limitations in the literature regarding IMT. IMT appears to improve dyspnea, waking test distance, and health-related quality of life in individuals with COPD, but it is not clear whether this improvement is mediated through improved inspiratory muscle strength and endurance. This review discussed several considerations critical to the design of future trials.

Exercise training in patients with pulmonary arterial hypertension: a case report.

PURPOSE: To describe the benefits of a feasible, outpatient exercise training program on exercise tolerance and health-related quality of life (HRQL) in individuals with pulmonary arterial hypertension (PAH). METHODS: Case report on two subjects recruited from a tertiary care pulmonary hypertension clinic. Subject 1 was a 50-year-old male with idiopathic PAH. Subject 2 was a 54-year-old female with a 20+ year history of scleroderma and 6-year history of PAH. Both subjects underwent exercise training 3 times per week for 6 weeks using a cycle ergometer at workloads progressing from 50% to 80% of peak workload. Outcomes were assessed using cardiopulmonary exercise testing, six-minute walk test (6MWT), and HRQL using the Chronic Respiratory Disease Questionnaire (CRQ) and the Cambridge Pulmonary Hypertension Outcome Review (CAMPHOR). RESULTS: Both subjects made substantial improvements in oxygen consumption and workload at anaerobic threshold (improvements of 3.8 and 4.2 mL.kg(-1).min,(-1) 26 and 18 W, respectively) and 6MWT distance (from 496 to 586m and 416 to 517m, respectively). Only Subject 1 made substantial improvements in peak oxygen consumption (from 16.0 to 18.3 mL.kg(-1).min(-1)and from 15.0 to 15.6 mL.kg(-1).min,(-1) respectively) and peak work rate (from 112 to 130W and 66 to 69W, respectively). Both subjects demonstrated improved HRQL. No adverse events were noted. CONCLUSIONS: A short and practical exercise training program can improve measures of workload, aerobic capacity, and HRQL in individuals with PAH with no adverse effects shown in these two case studies.
